New spkg:
http://www.risc.jku.at/research/combinat/software/ore_algebra/ore_algebra-0.2.spkg
This should be copied to the mirrors. Since it is an old-style spkg, no
modifications to Sage are needed.

Comment:
So we should be able to solve this by upgrading to version 0.2. I took a
look at 0.2, and it imports without breaking. Not everything works,
though, and I wish it had functioning doctests or a functioning test
suite, or both. A quick example, taken from the file `nullspace.py`:
{{{
sage: my_solver = cra(kronecker(gauss()))
sage: A = MatrixSpace(ZZ['x', 'y'], 4, 5).random_element()
sage: V = my_solver(A)
}}}
produces a `TypeError` for me (with Sage 6.5.beta0):
{{{
TypeError: x must be one of the generators of the parent.
}}}
Oh well. Let's upgrade on this ticket. Later on, we might consider
changing this to a new-style spkg, but that can wait.
Shall I give this a positive review?
